Gastrointestinal lymphomas in Hong Kong Chinese

Forty-six Chinese patients with primary gastrointestinal lymphoma were analyzed. The most common presentations were with abdominal pain, bleeding or a palpable mass. Only one case resembled the pattern of the so-called "Mediterranean lymphoma." The most common primary sites were the stomach and the ileum. One case of colonic lymphoma was associated with schistosomiasis but was probably not etiologically related. The pattern of primary gastrointestinal lymphoma in Chinese corresponds in general to the pattern observed in western countries.
